Works perfect. No more fan crazinessI replaced my 2009 iMac BTO 2.8ghz he'd with a SSD last year and had the wailing fan until installing dubious fan control software. That got weird so I bought this kit with the temperature sensor and now my iMac works as it should. Fast and snappy and fan only comes on audibly when doing heavy computer work as it should. Great product at an almost very reasonable price.

Worked like a champUpgraded to 2TB SSD in my '09 iMac, but without a temp sensor, the fan was running full blast all the time. It only took me 10 minutes to crack it open and slip this cable on - now the Mac is quiet as a mouse, which is an unexpected benefit of moving to an SSD. B&H had a great price and was prompt and efficient in shipping - I couldn't be happier with this purchase...

Works as expectedThis is a must for iMacs when you change the hard drive to one that does not have the temp sensor. Make sure you Id your iMac and get the system spec one. It's a. It cheaper at B&H than OWC. There are instructional videos on Macsales web page. Highly recommended

Works as advertised; easy to installI;m not sure what else to say.� If you are installing a 3rd party harddrive or SSD in a 2009-2010 iMac, you want this sensor, and it does what it says on the box: it senses temperature, and tells your mac not to run the fans at 100% unless needed.
